The lightning flash with arrowhead symbol within an equilateral triangle is
intended to alert the user to the presence of uninsulated “dangerous” voltage
within the product's enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to humans.
The exclamation point within an equilateral triangle is intended to alert the user
tothe presence of important operating and maintenance (servicing) instructions
in this manual.
The lightning flashes printed next to the output terminals of the amplifier are
intended to alert the user to the risk of hazardous energy. Output connectors
that could pose a risk are marked with the lightning flash. Do not touch output
terminals while amplifier power is on. Make all connections with amplifier
turned off.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE
COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALI-
FIED PERSON NEL.
WARNING: To prevent fire or electric shock, do not expose this equipment to
rain or moisture.
This amplifier has a serial number located on the rear panel.
Please write this and the model number down and keep them for your records.

·the screen is showed as follow:
Main volume will be saved automatically after 10 seconds' absent operation
after adjusting CH1-CH8 channel volume, the screen will go back to main volume
after 7 seconds. Volume will be saved automatically after 10 seconds' absent operation
the saved volume will be used when the amplifier is turned on next time

XLR INPUTS
1. Balanced input connections
XLR input connectors are electronically balanced;
XLR input connectors should be wired as follow:
Pin 1 Groud/ shield
Pin 2 positive (+)
Pin 3 negative (-)
2.Unbalanced input connections
To connect an input to an unbalanced source, it is possible to connect Pin1 and Pin3 in the XLR
plug at the amplifier end of the cable. However, a better method is to connect Pin3 to the shield at
the sourse end of the cable, as this usually results in better hum and noise rejection. Balanced input
connetions are recommended whenever possible.
OUTPUT TERMINAL SAFETY WARNING!
Do not touch output terminals while amplifier power is on.
Turn off the amplifier before connecting, or else there will be risk
of hazardous energy!
There's no bridge mode on this amplifier, and it can't work under 4 ohms load.
Do not support hot-plugging. Only plug in or out input signal when the power is off.
Overheat situation
the amplifier will protect itself when the temperature is too high
or the amplifier works overloaded at low impedance.
when the temperature is less than 60 degree centigrade, the
fans work at low speed.
when the temperature is between 60-95 degree centigrade, the
fans work at high speed.
when the temperature is over 95 degree centigrade, that
channel will stop output

Binding post output
each channel accept regular 2-wire cord, the red wire connects the
positive pole of the speaker, and the black wire connects the negative pole.
Each channel is with a balanced XLR input connector. it can be connected by standard wire.
it’s sugguested that to use balanced connector so as to reduce the AC noise and disturb,
especially when using long wire.Unbalanced connect is suitable when using short wire, and the
signal source impedance should lower than 600ohm.
